CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

An Active Debug Code vulnerability in certain ASUS router models allows a remote authenticated user, via a crafted HTTP request, to bypass security mechanisms and enable the Telnet service, thereby executing arbitrary commands with root privileges and potentially affecting other devices connected to the router. Refer to the ' Security Update for ASUS Router Firmware ' section on the ASUS Security Advisory for more information.
